The Impact of Images on Reading

"Students who visualize as they read not only have a richer reading experience but recall what they have read for longer periods of time."
(Harvey & Goudvis, 2000)

“…students who learned with words and pictures generated 89% more creative solutions to problems than did students who learned with words alone.”

The Pictorial Superiority Effect

The Picture Superiority Effect refers to the phenomenon in which pictures and images are more likely to be remembered than words.

“Based on research into the Picture Superiority Effect, when we read text alone, we are likely to remember only 10 percent of the information 3 days later. If that information is presented to us as text combined with a relevant image, we are likely to remember 65 percent of the information 3 days later.”
- John Medina, Brain Rules, 2008

Allan Paivio's dual-coding theory is a basis of picture superiority effect. Paivio claims that pictures have advantages over words with regards to coding and retrieval of stored memory because pictures are coded more easily and can be retrieved from symbolic mode, while the dual coding process using words is more difficult for both coding and retrieval. Another explanation of the higher free call in picture superiority is due to the higher familiarity or frequency of pictured objects (Asch & Ebenholtz, 1962).
